VENTILATOR Filed July 11, 1942 INVENTOR J'am es Hf. JMSG'Z arZZancZ WITNESSES I BY I Patented Oct. 17, 1944 UNITED STATES I PATENT OFFICE VENTILATOR James H. McPartland, St. John, New Brunswick, Canada Application July 11, 1942, Serial No. 450,549

5 Claims. (Cl. 98-63) This invention relates to ventilators, and more particularly to a ventilator which is adapted to either draw air from a building, hold, or other compartment, Or cause air to be forced into said compartment.

An object of the invention is to provide a simple but efficient ventilator of the type indicated, which may readily be installed in existing constructions withoutdifliculty or major alterations.

A further object is to provide a ventilator of the class described for use in connection with large areas, such as buildings or ships holds, and which may be used in combination with other identical ventilators to provide a complete ventilating system which will not only draw air out of the chamber but will at the same time introduce new air into the chamber.

A further object is to provide a ventilator of the type described, which will be automatically controlled by the wind and which will not be easily affected by back drafts or cross currents.

My improved ventilator is particularly adapted to ships since it will readily swing into a position where it Will collect the greatest amount of air in order to perform its function most efliciently.

In the drawing Fig. 1 is a side elevation in section showing a preferredform of my invention installed, with the dotted lines indicating the operation of the invention when it is desired to draw air out of the compartment;

Fig. 2 is a view similar to Fig. 1, showing the ventilator setto force air into the chamber to be ventilated;

Fig. 3 is a plan view of my ventilator;

Fig. 4 is a side view thereof.

In the accompanying drawing in indicates a ventilating pipe from a hold or other chamber, which extends through the roof or deck II. My ventilator l2 consists of a pipe I4 adapted to be positioned within the pipe I and carrying a ball bearing ring or collar I5 upon which the bottom plate l6 rests against the top 'of the pipe Iii.

The main body of the ventilator consists of an invertedfunnel-shaped member I! which is joined to the bottom plate I6 and which is straightened at E8 to form a neck providing an outlet opening above the top [9 of the pipe l4.

A fin or rudder 20 extends from the inverted funnel-shaped member l1 and a continuation thereof 2| is provided with a ring 22 encircling the pipe l0. Bracing elements23 may engage the bottom plate It to steady the rudder or fin.

It will be readily appreciated that the entire ventilator is adapted to readily rotate around the pipe I0 and that the greater portion of the weight is borne by the ball bearing collar I5.

At a point opposite the rudder 20 the member I! is cut away to form the door compartment 25 providing an air inlet at the bottom and side of the member H. A door or shutter 26 is hinged to the compartment 25, at 21, to control the inlet of air. An operating handle or bar 28 having a cross piece 29 extends outwardly from the door 26. The top inverted funnel-shaped member 11 is provided With a door or closure 30 hinged thereto at 3| to control the outflow of exhaust and is provided with a loop or hinge member 32 to which is hinged the connecting member 33. The connecting member 33 is provided with two flange-shaped members 34 and 35 adapted to engage the cross piece 29 or the edge 36 of the door 26. The door 26 is keyed to the pintle 43 of the hinge 21, and the outerend of the pintle is provided with a sprocket 4| on which thechain 42 operates. A control rod 43 is linked to the outer end of the operating member 33 so that it may be controlled from some distance. 7

When it is desired to draw air from the compartment to be ventilated, it is necessary to open both of the doors 2B and 30. This is done by connecting the operating member 33 to the member 28 and placing the cross bar 29 between the flanges 34 and 35. The sprocket 4| is then turned by the chain 42 and when the door 26 has been sufiiciently opened carrying with it the door 30 (as indicated by the dotted lines in Fig. l), the door is fixed against further movement by passing the pin 45 through a link in the chain 42. It will readily be appreciated that the degree to which the door 36 is to be opened with relation to the door 26 may be adjusted by placing the' cross bar 29 either between the flanges 34 and 35 or behind the flange 35. This adjustment is desirable to compensate for the force of the wind. Since the prevailing wind acting on the rudders 20 and 2| will cause the ventilator to swing into the wind, the wind will enter the member 27, circulate around the pipe l4, particularly around the upper end l9 thereof, through the neck l8, and pass out through the opening 38, thus causing enough draft of air through the pipe l4 and the pipe I0 and necessarily an updraft from the chamber to be ventilated.

When it is desired to use the ventilator to force air into the compartment to be ventilated, the operating member may be freed from the cross bar 29 and the door 26 opened by means of the chain 42. If desirable, the door 26 may be held in an open position (as indicated in Fig. 2) by hooking the edge of the door 26 under the flange 35. This leaves the door 30 closed and the air passing into the member I! will be forced down the pipe 14 through the pipe l into the chamber to be ventilated.

It will be appreciated that where a large hold or building is to be ventilated, the ventilators at one end thereof may be set to take in air while the ventilators at the other end thereof may be set to draw out air, thus forming a complete ventilating system. It will also be appreciated that many adjustments of the ventilator may be made to control the amount of air taken in or drawn out depending upon the strength of the wind, temperature, etc.

I claim:

1. A ventilator adapted for use with a vent pipe, including a pipe adapted to fit in telescoping relation in said vent pipe, a cone member rotatably mounted on said vent pipe, said second pipe extending into said cone member with its inner open end in spaced relation thereto, said cone member having an air inlet at the side and an exhaust outlet at the top, a bottom closing said cone member, doors on said cone member controlling said inlet and outlet respectively, an air fin on said cone member diametrically opposite said inlet, and means for opening either or both of said doors independently or jointly to allow the ventilator to draw air from or force air into said vent pipe.

2. A ventilator adapted for use with a vent pipe, including a pipe adapted to fit in telescoping relation in continuation of said vent pipe, a rotatable cone member on said vent pipe, said second pipe extending into said cone member with its inner open end in spaced relation thereto, said cone member having an air inlet at the side thereof, a bottom closing said cone member, a neck on the top of said cone member forming an exhaust outlet adjacent the top of said second pipe, doors on said cone member and neck respectively controlling said inlet and outlet respectively, an air fin on said cone member diametrically opposite said inlet, means for opening the door controlling said inlet to allow air to pass into said cone member and down said second pipe, and additional means to open said doors jointly to allow air to pass into said cone member and out of said outlet to draw exhaust air from said vent pipe through said second pipe.
